Frequently Asked Questions

What is the difference between interest rate and APR?
The interest rate prices the borrowing itself; APR also spreads one-time fees (origination, points, closing costs) across the term. Two loans at 6.5% can have APRs of 6.6% and 7.1% — the APR reveals the truly cheaper one.
Why is APR higher than the note rate?
Because you effectively receive less than you repay: fees reduce the money in your pocket, but payments are computed on the full amount. The gap is largest on short loans with big fees.
Is APR the full story?
Almost — APR assumes you keep the loan to term. If you will sell or refinance early, upfront fees hurt more than APR suggests, so low-fee loans win for short horizons.
